Description

Pure electric vehicles structure is reequiped to traditional internal-combustion engine car

Technical Field

The utility model belongs to the technical field of automobile power, especially, relate to a pure electric vehicles structure of traditional diesel locomotive repacking.

Background

Fig. 1 is a schematic diagram of a conventional gasoline and diesel engine. Usually, a cylinder and a cylinder cover form a cylindrical closed cavity, and a cylindrical piston is arranged in the cavity and can freely slide up and down; the piston is connected with the crankshaft through a connecting rod, and the reciprocating motion of the piston is converted into the circular motion of the crankshaft; liquid lubricating oil is arranged between the piston and the cylinder wall, so that the friction resistance is reduced; usually, the crankshaft is connected to a coaxial flywheel, and the flywheel with certain mass can smooth the vibration of the system. The space between the piston and the cylinder is a combustion chamber, and the spark plug ignites combustible mixed gas in the combustion chamber at a proper time to drive the piston to move downwards so as to apply work to the crankshaft.

In practice, if a traditional internal combustion engine automobile needs to be transformed into a pure electric automobile, the common method is to remove an engine and a matching system thereof, and then arrange a motor, an inverter and a battery pack, so that the whole scheme is complex and high in cost. The utility model discloses a do the change of minizone to original internal-combustion engine, realize pure electric drive scheme.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a pure electric vehicles structure of traditional diesel locomotive repacking reduces repacking cost and reduces the repacking complexity.

In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a pure electric vehicles structure is reequiped to traditional diesel engine car, this pure electric vehicles structure is reequiped to traditional diesel engine car includes cylinder head, solenoid, permanent magnet, piston, connecting rod, flywheel, bent axle, the solenoid is fixed in the cylinder head upper end, and the piston is close to cylinder head end and inlays and establish the permanent magnet, and permanent magnet end hinge joint connecting rod is kept away from to the piston, and the flywheel is connected to the connecting rod other end hinge, and fixed bent axle is located to the flywheel axle center.

Preferably, the permanent magnet magnetic pole is disposed toward the cylinder head end.

Preferably, the solenoid is connected to a drive circuit, and a direct current is applied to the solenoid when the piston is near top dead center, ensuring that the magnetic field generated by the current is opposite to the permanent magnet magnetic field on the surface of the piston.

The utility model has the advantages that: according to the structure of the pure electric vehicle refitted from the traditional internal combustion engine vehicle, the cylinder cover and the piston of the traditional internal combustion engine are improved by adding the solenoid and the permanent magnet, and on the premise of not needing a motor and an inverter, only the battery and the simple control circuit are added, so that the pure electric vehicle refitted from the gasoline vehicle and the diesel vehicle is realized, and the cost and the construction difficulty are greatly reduced; meanwhile, because the solenoid is of a hollow structure, the original combustion chamber is communicated with the atmosphere, the original cylinder cover of the internal combustion engine can be disassembled and replaced by a new cylinder cover with a solenoid electromagnet, the gas distribution devices such as an inlet valve and an exhaust valve can be eliminated, and the cost is reduced.

Detailed Description

In order to further understand the contents, features and functions of the present invention, the following embodiments are illustrated and described in detail with reference to the accompanying drawings.

Referring to fig. 1 to fig. 3, a structure of a pure electric vehicle modified from a conventional internal combustion engine vehicle according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

As shown in fig. 2, the structure of the modified pure electric vehicle of the conventional internal combustion engine vehicle comprises a cylinder cover 1, a solenoid 2, a permanent magnet 3, a piston 4, a connecting rod 5, a flywheel 6 and a crankshaft 7, wherein the solenoid 2 is fixed at the upper end of the cylinder cover 1, the end of the piston 4 close to the cylinder cover 1 is embedded with the permanent magnet 3, the end of the piston 4 far away from the permanent magnet 3 is hinged with the connecting rod 5, the other end of the connecting rod 5 is hinged with the flywheel 6, and the crankshaft 7 is fixed at the axis of the flywheel 6.

Specifically, the magnetic poles of the permanent magnets 3 are disposed toward the cylinder head 1 end.

Specifically, as shown in fig. 3, a drive circuit is connected to the solenoid 2, and when the plunger 4 is near the top dead center, a direct current is applied to the solenoid 2 to ensure that the magnetic field generated by the current is opposite to the magnetic field of the permanent magnet 3 on the surface of the plunger 4.

In the above embodiment, the driving circuit generates a circuit to charge the solenoid 2, and when the current direction of the driving circuit is changed, the direction of the magnetic field generated by the solenoid 2 is changed to repel and attract the permanent magnet 3, so that the reciprocating motion is performed, and further, the piston 4 reciprocates up and down, and the connecting rod 5 drives the flywheel 6 to rotate, thereby outputting the driving force through the crankshaft 7.
